DIREGTION-INDICATOR FOR VEHTCLES.

Application filed March 1.

To all whom it may concern:

Be it known that we. Ciiins'rorii'i-ui .pecification of Letters Patent;

O'Ni-nm. (itowiinv and llitxav Atria-1n LAM, 1 sub ects of the King of the lfnited Kingdom of Great Britain and Ireland. both residing at London. England, have invented a certain new and usetul Improvement in Direction- Indicators for Vehicles, of which the folany desired part of the vehicle. for instance lowing is a specification.

This invention relates to improvements in apparatus applicable to vehicles for instance. to a mechanically driven vehicle for indicating for instance to following vehicles 'a plurality of signs, 5. e. the next variation in the movement of the vehicle, as regards direction and as regards stoppin The indications to be given by such'apparatus are whether the vehicle is next to be i moved to the'right or to the left or is to he stopped. It is assumed that when the vehicle is traveling at what may be supposed to be a normal rate no indication regarding such movement need be given.

The improved apparatus is illustrated in' the accompanying drawings in which Figure 1 is a side elevation of a motor driven vehicle equipped with the improved apparatus. Fig. 2 is a front elevation of the casing containing the indicating devices and Fig. 3'is a like view to Fig. 2 but shows the front cover removed. Fig. 4 is an elevation of the casing at right angles to Fig. 2. with the end cover removed. Fig. 5 is a sectional plan of the indicating devices and relative connections. Fig. 6 shows a detail of one of the indicating devices and its operative connections. Fig. 7 shows a modification.

Referring to Figs. 1 to 6, at the rear or other part of the vehicle A is fitted a casing B, so that the ends of the casing shall not project laterally from the vehicle. The said casing B is partly cut away at the front, and within the casing are fitted movable devices which serve to afford the indications above referred to. These devices comprise plates C, D and E, the plates C and D being of arrow shape and pointing to the right and to the left respectively, while the plate E is cut to present the word Stop." All of the said devices are wholly inclosed within the casing B, with no projecting parts and are all normally concealed from view.

As shown, the casing B is provided with a transparent pane b visible at the rear of the vehicle A and with a suitable ackground in front of which the plates t. I)

5 and E'niove; For instance, the plates may ho hlaclvenetl 'and the back-ground formed hr :1 white opal {Ila-s plate F behind which' plate a light may be located to illuminate the plate at night. .g remgxable lamp is shown at (iii As heretofore. connections are provided for controlling the indicatin devices from i from a position adjacent the driver's seat or the steering column: the movement imparted to the plates being in the pre-ent ca e a vertical reciprocating movement for which purpose we provide suitable guide within the casing. As shown. each of said plates is adapted to be reciprocated by means of the slotted end 11 of a double-arnu-d pivoted lever H engaging a pin it on each plate. the ends of said plates being guided b v stationar bars or rods I, the desired movement being imparted by means of flexible wires J. c. y Bowden wires such as heretofore emplojved. said wires acting against springs K connected to the levers H and to the easing B.

\Ye also provide a hell or the like opera- .tively connected with the mean for moving the indicating devices. to give a warning when any one of the indicating devices is bein operated. As shown. the bell L is 10- catec within a perforated casing 7. the ham: 'mer connection I being operated b v a lever arm at on a rock shaft M to each end of which shaft is secured a lever an adapted to be actuated through the intermediary of stops j connected to the ends of the levers H and movable by the wires J.

The indicating devices above described may be used in conjunction with the devices for showing the registered number of the vehicle to which they are fitted 'the lamp for illuminating the indicating devices serving also as the tail lamp for the vehicle.

As shown .in Fig. 7. the device for showingthe aegistered number of the vehicle may comprise a casing N having a whiteopal or like glass plate a on which the number is indicated. preferabl in black. said casing being mounted on the casing B which may be provided with a ruby or other glass plate disposed behind the indicating plates. a

adapted to illuminate them when desired.

It will be observed that the said indicating devices are separately movable into one and the sameposition so that the driver of a lamp located behind said glass plates being following vehicle for instance need only direct his eye to one point in the vehicle in front.

Having now described our invention what. we claim and desire to secure by Letters Patent of the United States is Apparatus for indicating variations in the movement of a vehicle, comprising, in combination, a casing having an aperture, vertical guides fitted within the casing, a plurality of indicating devices wholly contained within the casing. iivoted levers for moving'said indicating cevices independently in said guides into the same indicat- 15 ing position opposite the aperture, springs connected to said pivoted levers and to the casin flexible means connected to said pivoted levers, stops on said flexible means, a 'ock shaft, lever devices secured to said rock shaft and adapted to be operated by said stops, and bell operating mechanism in' operative relation with said lever devices.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
